PURPOSE ^

FILTTAPPERED - filters with cosine tappering at ends.

SYNOPSIS ^

function x2 = filttappered( b, a, x1 );

DESCRIPTION ^

 FILTTAPPERED - filters with cosine tappering at ends.

 Usage: x2 = filttappered( B, A, x1 )

 where B and A are explained in the filter function.

 Normally for this function, A is a scalar.  Not sure what it does if it
 isn't.

 This function also assumes that B is a symmetric set of weights.
